this is something I have been meaning to ask for some time now....I bought my testkit in Holland and I am wondering if the chart is the same for the kits bought here (I am pretty sure they are). The reason I am asking is that for the high reputation that these testkits have, I am astounded that the breakdown on the color chart is so broad 7.4-7.7-8.0-8.3-8.6 with no in between numbers and the colors still being pretty close..
